Only to the former. If it is actually possible to print a stack trace,
that could be useful indeed. I'm then skeptical that this is possible
in the general case (i.e. displaying the full C stack), but displaying
(parts of) the Python stack might be possible. I think it should still
proceed to dump core, so that you can then inspect the core with a
proper debugger.
